Dizziness is a common presenting complaint to the emergency department (ED), and emergency physicians (EPs) consider these presentations a priority for decision support. Assessing for nystagmus and defining its features are important steps for any acute dizziness decision algorithm. The authors sought to describe nystagmus documentation in routine ED care to determine if nystagmus assessments might be an important target in decision support efforts. ⋯ Nystagmus assessments are frequently documented in acute dizziness presentations, but details do not generally enable a meaningful inference. Recorded descriptions usually conflict with the diagnosis when a peripheral vestibular diagnosis is rendered. Nystagmus assessments might be an important target in developing decision support for dizziness presentations.

Randomized Controlled Trial
A randomized controlled trial of capnography in the correction of simulated endotracheal tube dislodgement.
Unrecognized dislodgement of an endotracheal tube (ETT) during the transport of an intubated patient can have life-threatening consequences. Standard methods to monitor these patients, such as pulse oximetry and physical examination, are both subject to inaccuracies with patient movement and ambient noise. Capnography provides a continuous and objective measure of ventilation that can alert a provider immediately to an airway problem. The objective of this study was to determine through simulation if capnography decreases time to correction of dislodged ETTs during the transport of intubated patients, in comparison to standard monitoring. ⋯ The addition of capnography to standard monitoring significantly improves recognition of ETT dislodgement and reduces the time to correction of dislodged ETTs by prehospital providers in a simulated pediatric transport setting.

Multicenter Study Comparative Study
Pediatric emergency health care providers' knowledge, attitudes, and experiences regarding emergency contraception.
The objective was to describe knowledge, attitudes, and experiences regarding emergency contraception (EC) among pediatric emergency health care providers (HCPs). ⋯ This study identified important HCP perceptions and barriers about EC provision in the pediatric ED. These findings may inform future efforts to improve EC provision for adolescents. Specifically, future studies to evaluate the differences in attitudes between nurses, physicians, and NPs, and the use of social judgment in EC provision, are warranted.

Randomized Controlled Trial
Predictors of 30-day cardiovascular events in patients with prior percutaneous coronary intervention or coronary artery bypass grafting.
Risk stratification of patients with potential acute coronary syndrome (ACS) is difficult. Patients with prior revascularization are considered higher risk, but they can also have symptoms from noncardiac causes. This study evaluated whether the presenting clinical characteristics were predictive of an increased risk of 30-day cardiovascular events in patients with prior revascularization presenting to the emergency department (ED) with symptoms of potential ACS. ⋯ In patients with prior revascularization, the initial ECG and early cardiac marker elevations, but not clinical presentation, predict odds of 30-day death, AMI, or revascularization.

Multicenter Study Comparative Study
Comparison of clinical performance of cranial computed tomography rules in patients with minor head injury: a multicenter prospective study.
The objective was to compare the predictive performance of three previously derived cranial computed tomography (CT) rules, the Canadian CT Head Rule (CCHR), the New Orleans Criteria (NOC), and National Emergency X-Ray Utilization Study (NEXUS)-II, for detecting clinically important traumatic brain injury (TBI) and the need for neurosurgical intervention in patients with blunt head trauma. ⋯ For clinically important TBI, the three cranial CT decision rules had much lower sensitivities in this population than the original published studies, while the specificities were comparable to those studies. The sensitivities for neurosurgical intervention, however, were comparable to the original studies. The NEXUS-II rule showed the highest reduction rate for CT scans compared to other rules, but failed to identify all undergoing neurosurgical intervention for their original inclusion cohort.
